MECHANICAL TROUBLESHOOTING
When presented with an EU7000is inverter generator exhibiting error codes or unusual running problems, follow the
steps below BEFORE troubleshooting by the error code(s) found in the EU7000is Shop Manual or the EU7000is
section of the Generator Troubleshooting Guide.
Remember, mechanical problems can lead to error codes and replacement of expensive electronic components that
may not be faulty. Some of these steps, hints, and directions may seem irrelevant or an inefficient use of time. It has
been shown that following these steps leads to easier and earlier identification of the actual problem or faulty
component.
Follow these steps and, when necessary, contact Techline or your District Service Manager (DSM) if additional
assistance is necessary. Always complete sections 1 and 2 before calling.
REMINDER: All major component replacement requires prior warranty authorization from Techline or your DSM. Major
components include the inverter, generator control unit (GCU), stator, rotor, and major engine components.
It may not be necessary to perform all of the following troubleshooting steps:
• Always complete sections 1 and 2.
• If the generator starts and immediately stalls or runs less than 10 seconds, refer to sections 3 to 5.
• If the generator runs for more than 10 seconds, refer to sections 6 and 7.
1. QUESTION THE CUSTOMER
When an EU7000is generator is brought in for
repair, be sure to fill out the i-Monitor Detail Error
Log found at the end of this job aid. This document
is required before Techline or your DSM can
authorize warrantable inverter generator repairs.
Important information to get from the customer:
• Description of generator usage at the time of
the failure
• Receptacles used
• Loads (manufacturer, model, volts, and
amps of each load)
• Extension cord length and gauge
2. CHECK THE CONDITION OF THE GENERATOR
With the customer present, document the condition of the fuel,
oil (level, color, odor) and air filter.
